This changes libcc1 to use std::vector in the code that builds
function types.  This avoids some explicit memory management.

libcc1/ChangeLog
2021-01-03  Tom Tromey  <tom@tromey.com>

	* libcp1plugin.cc (plugin_build_function_type): Use std::vector.
	* libcc1plugin.cc (plugin_build_function_type): Use std::vector.
